Needle Roller Bearing

Long thin rollers deliver very high load capacity in an extremely compact radial envelope where space is at a premium.

Technical Overview

Needle Roller Bearings use elongated cylindrical rollers with a very high length-to-diameter ratio. This unique geometry delivers surprisingly high radial load capacity for their bore diameter — making them the preferred choice wherever radial space is limited but load is significant.

They are available in a wide range of configurations: drawn cup (HK/BK) with or without inner ring, machined ring types (NA/RNA) with or without inner ring, and track rollers/cam followers. The IKO and INA brands specialise heavily in needle roller bearings and AMFO Traders stocks both.

These bearings are used extensively in automotive transmissions, printing machinery, textile frames, and two-stroke engines — wherever you need to pack a large bearing into a small space.

Other Bearing Types

View all →

Deep Groove Ball Bearing

The most widely used bearing type globally. Handles both radial and axial loads in both directions with minimal friction.

Self Aligning Ball Bearing

Two rows of balls with a spherical outer raceway. Automatically compensates for shaft misalignment and angular deflection.

Angular Contact Ball Bearing

Designed for combined radial and high axial loads. The contact angle defines the axial-to-radial load ratio.
